For light or ultraviolet, the formula for energy can be
calculated using Planck’s equation. That is:
E = h c / ʎ
where,
h is the Planck’s constant = 6.626 * 10^-34 m^2 kg
/ s
c is the speed of light = 3 * 10^8 m/s
ʎ is the wavelength of light = 110 nm = 110 x 10^-9 m
So calculating for energy E:
E = (6.626 * 10^-34 m^2 kg / s) * (3 * 10^8 m/s) /
(110 x 10^-9 m)
E = 1.807 x 10^-18 J
Answer:
The intensity of sound at rock concert is 10¹⁰ greater than that of a whisper.
Explanation:
The intensity of sound is given by;
where;
I is the intensity of the sound
I₀ is the threshold of sound intensity = 1 x 10⁻¹² W/m²
The intensity of sound at a rock concert
The intensity of sound of a whisper
Thus, the intensity of sound at rock concert is 10¹⁰ greater than that of a whisper.
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun, and the rotation of the Earth. Tide tables can be used to find the predicted times and amplitude (or "tidal range") of tides at any given locale.
